Inquiry Submission By warren e

My wife and myself (70 years old) plan on hiring a car to drive us from Phnom Penh to Siem Reap on February 19th. How safe is the trip, what is the approximate cost, & where is the best place to book the car transportation?? We have traveling in Asia for the last 14 days on our own and will be flying into Phnom Penh

Thank You
